If Cork line out as selected then I cannot see them winning especially as Donnacha O'Connor is injured and they are only playing Shields from the U21's. Cork have decent enough backs but the forwards are weak both in terms of creating and taking scores - they need twice as much possession as the other team. Even against Tyrone there was only two points in it when Mulligan was sent off and also Tyrone had to replace their two corner backs. Tyrone more or less gave up in the last 15 mins and it was easy for Cork to get some handy points. If Mayo break even at midfield they should win as I cannot see Cork scoring more than 9 or 10 points and Mayo are capable of 1-12 or 1-13. Forecast is for dry weather which will test the cork backs..the night against Tyrone pitch was heavy and it was more suited to backs.
